document and set to the required offset.
(9) If 5-carrier offset is required, restore the carrier offset using the following routine:
❑ Connect a 50 ohm frequency counter, through a 60 dB attenuator, to the transmitter’s rear
panel Antenna connector (see Fig 1 for location of the Antenna connector).
❑ Refer to AM Voice Mode Settings Screen in the Operation section of this document and set
the desired 5-carrier offset.
❑ Refer to Changing the Transmitter’s Operating Frequency in this document and set the
transmitter to the nearest 25 kHz channel frequency. For example, if the required frequency
is 124.504 (+4 kHz offset), set the transmitter to 124.500 MHz.
❑ Key the transmitter and adjust the reference frequency, using the front panel Scroll/Select
control, until the frequency counter displays the required operating frequency. For example
124.504 MHz.
❑ When the frequency counter displays the exact operating frequency, press the Scroll/Select
control and stop keying the transmitter.
❑ Disconnect the test equipment and reconnect the antenna.
